Frequently Asked Questions

Q. Why doesn't Stockfish have a fixed Elo rating?

Unlike human players, Stockfish's Elo rating is highly dependent on the testing conditions. Factors such as hardware (CPU cores, clock speed, RAM), time control, operating system, and even the specific version of the engine significantly affect its performance. A faster computer with more cores will produce a higher Elo rating.

Q. Why is Stockfish's Elo rating so incredibly high?

Stockfish 18 operates on an entirely different level compared to humans. While the best human players rely on intuition and pattern recognition, Stockfish calculates millions of positions per second with near-perfect accuracy.
